Stem Cells and Public Policy
By: Natalie Whitney
Stem cells be a steady rising base in public policy here in the get together States. Research on stem cells is supposed to about travel our k at one timeledge about how we go off prepare an organism from whiz cell and how its cell can later be employ to help adult organisms. Scientists argon investigating this possibility of cell-based therapies to serve diseases such as diabetes and Parkinsons disease. Like a mess of former(a) expanding fields of scientific discovery and research, research on stem cells raises lots of questions regarding life--when it begins, and who can play with it. The government has now set limits on stem cell research, but is it authentically putting us behind on medical discoveries?
First to volunteer some background I think it is best to condone what stem cells are, why they are important, and what they are supposed to be used for. Stem cells have the capacity for prolonged self-renewal and can produce at least one type of passing differentiated descendant (Holland). Stem cells are also referred to as human embryo stem cells or hES. In adults, they are present in many tissues or cells such as bone marrow. hES cells have two important characteristics that distinguish them from other types of cells.
Stem cells are able to renew themselves for long periods finished cell division and they can be made to plough cells with special functions like the insulin-producing cells of the pancreas or the beating cells of the heart muscle. The hES cells are most important because they are pluripotent--they are able to develop into many types of tissues. They are also immortal--able to continue dividing indefinitely without losing their genic structure (Holland). They can be manipulated without losing cell function. All of these qualities wreak the study...
